Solving
2 + 1x + 2x2 = 0

Solving for variable 'x'.

Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
1 + 0.5x + x2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + 0.5x + -1 + x2 = 0 + -1

Reorder the terms:
1 + -1 + 0.5x + x2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 0.5x + x2 = 0 + -1
0.5x + x2 = 0 + -1

Combine like terms: 0 + -1 = -1
0.5x + x2 = -1

The x term is 0.5x.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5x + 0.0625 + x2 = -1 + 0.0625

Reorder the terms:
0.0625 + 0.5x + x2 = -1 + 0.0625

Combine like terms: -1 + 0.0625 = -0.9375
0.0625 + 0.5x + x2 = -0.9375

Factor a perfect square on the left side:
(x + 0.25)(x + 0.25) = -0.9375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
